France reached their third World Cup final after overcoming Belgium on Tuesday, sparking scenes of unconfined joy in Paris as tens of thousands of people poured into the streets.

In scenes reminiscent of France's 1998 World Cup win, delirious crowds surged up the Champs-Elysees avenue and surrounded the Arc de Triomphe, waving flags and letting off flares.

A header from Samuel Umtiti in Saint Petersburg was enough to give Didier Deschamps' team a 1-0 win against Belgium.

The 49-year-old coach is now just one win away from winning the World Cup -- 20 years after he captained the team to victory on home soil.

The tournament favourites must wait 24 hours to discover whether they will play England or Croatia in Sunday's final in Moscow's Luzhniki Stadium but they will approach the game brim full of confidence.

Belgium started the stronger of the two teams but Umtiti's header from a corner in the 51st minute was the pivotal moment as the defender stole the limelight from jet-heeled Kylian Mbappe and Antoine Griezmann.

France's other hero was goalkeeper Hugo Lloris, who made a spectacular fingertip save in the first half to deny Toby Alderweireld and then kept out Alex Witsel's drive as Belgium cranked up the pressure towards the end of the match.

Deschamps said he was delighted to have the chance to bury the pain of the Euro 2016 final, which Portugal won in Paris.

"I am very happy for my players," he said. "It was hard against a very good Belgium team. I take my hat off to my players and my staff."

"Finals have to be won because we have still not got over the one we lost two years ago," he added.

France started the tournament in Russia slowly, struggling for goals in the group stages but hit their stride in an impressive 4-3 victory against Lionel Messi's Argentina in the first knockout round.

Boasting an impressive combination of experience and youthful zest, they controlled their quarter-final against Uruguay, running out comfortable 2-0 winners.

The defeat is painful for Belgium, foiled at the semi-final for the second time in their history, as the clock ticks on their so-called "golden generation".

Captain Eden Hazard dazzled in patches but Kevin De Bruyne was quiet and Romelu Lukaku was a shadow of the player he had been earlier in the tournament, even though Belgium enjoyed most of the possession.

Martinez bemoaned the goal his team conceded from a corner.

"I couldn't ask more of the players' attitude," he said. "If you are going to have to lose such a match, which is bearable, it is the manner in which our players lost, pushing for everything, trying everything until the final whistle."

- England dream -

England face Croatia on Wednesday in the Luzhniki, seeking to reach their first World Cup final since 1966 against a background of near hysteria at home.

Manager Gareth Southgate said his inexperienced side must look to perform at their "regular level" despite the pressure.

Captain Harry Kane is leading England's charge with six goals so far, putting him top in the race for the Golden Boot.

England are in the last four of a major tournament for the first time since Euro '96, when Southgate himself missed a penalty in a shootout defeat against Germany.

He is now trying to minimise potential distractions as his young team prepare to take the next step in their bid to repeat their World Cup triumph at home 52 years ago.

"We're going into a semi-final but it just seems like it's the next step on the journey," he said.

"This team is nowhere near the level they're going to be capable of, partly because of their age and partly because over the next few years, with us and with their clubs, they're going to have more and more big-match experiences.

"So we're excited about the future but we also want to make the most of the opportunity we have tomorrow."

Croatia defender Dejan Lovren believes his tired team are ready to seize the opportunity of a lifetime.

It is the first time since 1998 that the nation of just over four million people have reached this stage of the competition, after they eliminated Russia in a penalty shootout at the weekend.

There are concerns that fatigue could be a factor for Zlatko Dalic's side, given they were forced to come through 120 minutes and penalties against both Denmark and the hosts in the last two rounds.

However, Liverpool centre-back Lovren does not think that will be a factor.

"I am perfectly ready and fit and I can say the same for my teammates. We know what it takes and in such moments you forget any fatigue you may feel," said the 29-year-old.

"This is maybe a once-in-a-lifetime opportunity. It may repeat itself once, maybe never."
